Natural history collections are invaluable repositories of biological information that provide
an unrivaled record of Earth's biodiversity. Museum genomics—genomics research using …

Microchromosomes are prevalent in nonmammalian vertebrates [PD Waters et al., Proc.
Natl. Acad. Sci. USA 118 (2021)], but a few of them are missing in bird genome assemblies …

Organismal adaptations are the hallmark of natural selection. Studies of adaptations in avian
systems have been central to key conceptual and empirical advances in the field of …

Genomic structural variants (SVs) play a crucial role in adaptive evolution, yet their average
fitness effects and characterization with pangenome tools are understudied in wild animal …

Background Divergence time estimation is fundamental to understanding many aspects of
the evolution of organisms, such as character evolution, diversification, and biogeography …

Complex patterns of genome evolution associated with the end-Cretaceous [Cretaceous-
Paleogene (K–Pg)] mass extinction limit our understanding of the early evolutionary history …

Understanding the mechanisms underlying species formation and differentiation is a central
goal of evolutionary biology and a formidable challenge. This understanding can provide …

The chicken continues to hold its position as a leading model organism within many areas of
research, as well as being a major source of protein for human consumption. The First …

The germline-restricted chromosome (GRC) is likely present in all songbird species but
differs widely in size and gene content. This extra chromosome has been described as …

In 2011, the first high-quality genome assembly of a squamate reptile (lizard or snake) was
published for the green anole. Dozens of genome assemblies were subsequently published …
